I'm not sure I'd call it "best", but it's definitely one of the more interesting ones that I've just never heard of anywhere else. I found it in an antique store like two decades ago: An Alien Light It's mostly from the perspective of primitive humans being studied by aliens while the aliens teach them various topics like math and science. The aliens are studying these lost tribes because out in space they're at war with humans and cannot figure out how the humans are able to fight each other and still be winning the war with the aliens.
